There are three doxologies currently listed in the 1990 Presbyterian hymnal, published out of Louisville, KY, hi, Jackie.
First version, #591 [I've never heard this one sung in church]
Praise God, from whom all blessings flow;
Praise Christ, all people here below;
Praise Holy Spirit evermore;
Praise Triune God, whom we adore.
Amen.
#592 [as mentioned in someone's post above]
Praise God, from whom all blessings flow;
Praise Him, all creatures here below;
Praise Him above, ye heavenly host;
Praise Father, Son, and Holy Ghost.
Amen.
#593 is like #592, but there are seven Amens.
In the Presbyterian church, the "Glory be to the Father" mentioned in a post above isn't referred to as the Doxology, but as the Gloria Patri--and there are quite a few versions of it in the hymnal.
Edit:
I just checked the index and there are quite a few other doxologies I've played in services, but never realized they were doxologies:
'All Praise to Thee, My God, This Night'--really lovely;
'Come, Holy Spirit, Our Souls Inspire'
'Creator of the Stars of Night'
'Of the Father's Love Begotten'
'What Star Is This, with Beams So Bright'
...I admit that I've never studied church music formally, so it's very interesting to see that hymns we sing have been classified by the church as doxologies--beyond the one we sing faithfully every week: #592.
